Q:$$5^{2}+6^{2}+7^{2}+\\cdots +15^{2}$$. 

P:To find the value of the expression 5^2 + 6^2 + 7^2 + ... + 15^2, we can solve them one by one and sum them:
    5^2=25,6^2=36,7^2=49,8^2=64,9^2=81,10^2=100,11^2=121,12^2=144,13^2=169,14^2=196,15^2=225
And then we can sum them:
    25+36+49+64+81+100+121+144+169+196+225=1210
Therefore, the value of the expression 5^2 + 6^2 + 7^2 + ... + 15^2 is 1210.

A:1210
